Abstract
Disclosed are a semi-transparent ceramic sheet decorated through ink light-absorbance and a preparation method thereof. The semi-transparent ceramic sheet comprises a semi-transparent green body, an inner inkjet pattern layer infiltrating into the semi-transparent green body from an upper surface of the semi-transparent green body, a decoloration glaze layer located on the upper surface, and a surface pattern layer located on the decoloration glaze layer. The decoloration glaze layer is capable of decoloring the ink of the inner inkjet pattern layer. The semi-transparent ceramic sheet is provided with the decoloration glaze layer so that the inkjet decoration of the inner inkjet pattern layer cannot be displayed on the surface, and the decorative pattern on the surface of the green body is the surface pattern layer and the inner inkjet pattern layer is completely in the inner layer of the green body.
